WORK-SUPPORT.

Original application led October 20, 1908,' Serial No. 458,630.` ,Renewed July 17, 1912, Serial Divided and this application filed .December 7, 1909.

To all 'whom t may concern.'

Be it known that I, WARREN FRAZIER, a citizenA of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in WorkSupports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to jacks such as are employed in shoe machines for supporting boots and shoes, and more particularly to a jack which has provision for adjustment to vary the position of the -shoe supported thereon. a

An object of the present inventiony is to provide an improved jack of the above type.

To this end the present invention consists in the improved device herein-after described and claimed.

`Referring to the drawings,-Figure 1 is a view in side elevation of a heel breasting machine provided with a jack embodying the present invention; Fig. 2 is a view in rear elevation of a portion of thejack shown in Fig. 1.

In the drawings the present invention is shown embodied in a heel breastingk machine ofthe type setforth in my Patent No. 1,068,423, granted July 29, 1913, of which the present application isa division.

f 2 denotes the frame ofthe machine which is provided with a reciprocating breasting knife 4 and a tread plate 6 for limiting movement of Vthe shoe toward the knife. In accordance with the present invention there is provided an improved` jack, for sustaining a shoe, which is arranged for adjustment to press the heel ofthe shoe against a tread plate 6 to properly position the shoe in operative relation to the breasting knife. The jack comprises'a post`8, adapted'to sus,- tain va shoe support, which is pivoted about a horizontal axis at 10 andl arranged for limited swinging movement about said axis, the extent of this movement being determined by the play of a projection 12 in a depression 14. The post 8 carries a vertically ad'-` justable rod 16 provided with arms 18 and 20,; carrying respectively a pin 22 to enter the 'opening' in the heel of the last'and a toe rest 24 for sustaining the toe of the last@ Specification of Letters Patent.

With this construction it will befseen'thatthe shoe support is adapted to have a 'swinging movement about the pivot 10 between an outer inclined position inwhich it m-ay retherein as by means of a Vlongitudinal slot 26 in the rod and a plate28 extending into' said slot and secured in the top of said post. A pinion 30 is supported upon the top yof the post 8, and

the rod 16 so that rotation of thepinion will ei'ect longitudinal movement of the rod.. Upward movement of the pinion 30 islref, strained by means of ngers' 32 secured toY the post and provided with projection'sgex-` tending into a peripheralgroove 34 formed in the hub` ofthe pinion. l A segmental rack 36 meshes with the has threaded .engagement with pinion and is rigidlyse! No. 710,059. l

cured to a hand lever 38 pivoted on the post l,

at 40, so that by moving said lever the operator may actuate the pinion `and raise or lower the shoe support, the arrangement being such thatv an inward movement of the'- lshoe supportV to r-be ,v

hand lever causes the raised.v

.x In the use of th ejack shown in the draw?,

ings, the last whichv carries theshoe is placed upon -the shoe support when the latter isrin its outer'inclined position. The j ack is then swung inwardly about the pivot 10 to posi,-

tion the heel of the shoe `in the path of the i breasting knife, and the shoe is raised by means of the lever 38 so that the tread of the heel strikes the plate 6 and said heel is irmly clamped between said plate and the ast.

It will be seen in the use of the'jack described that 'although movement may easily imparted to the shoe support by the hand lever 38 tov bring the shoe intol opera-W l tive relation to an operating tool the `fact that this movement is transmitted through; a pinion which has threaded engagementv with the supporting rod of the shoe support obviates any liability of the `shoe support yielding to the thrust of the breasting operation.

Having described my invention, what Iv claim as new and desire to secure by Letters Pat-ent of ,the United States is Efe knife in the y l.
